TQVOLZZ whom it may concern:

Beit known that I, ARGHIBLE M. HoRIoN, a citizen of the United States, residing at Saratoga, in the county of Carbon, Stateof Wyoming, have invented certain new and useful Improvelnents in Ooncentrating-'Amalga' mators, of which the followingis a specifica# tion,reference being hadv therein to the accompanying drawillgs.

This invention relates toconcentratingamalgamators, and particularly to a machine in 'Which the concentration is produced by centrifugal forcein the oscillatory movement of a receptacle.

The invention has for an object to improve the construction of the concentrating-cyliny der, whereby the amount of sediment collected in the bottom thereof Vmay be accurately regulated andthe discharge of this metal-bearing sediment controlled and determined relative to the character of ore operated upon. n t

A further object of the invention is to proed to be operated by centrifugal force, together with means for limiting the movement of this valve or holding the same against movelnent. Y e

A further object of the invention is to provide amalgamating means adapted to receive the waste material from the concentrating and amalgamatin g cylinder in order to determine the character of work performed by the cylinder and to recover any valuable metal which may be present in said waste' material. Other and further objects and advantages,

of the invention will be presented in the following description and the novel features thereof pointed out in the appended claims.

In the drawings, Figure 1 is a front elevation of the machine. Fig. 2 is a vertical section through one of the concentrating and amalgamating cylinders'. Fig. 3 is a plan ot' the machine. l Fig. t is a detail plan of the discharge-valve lwith parts in section broken away, and Fig. is a detail elevation of the adjustable'stopfrthe discharge-valve. Fig. 6 is 'a detailpl'an with the cylinder removed, an'dfhig. 7' is averti'cal section on the line 7 7 of Eig. 6 with cylinders in position.

Vtive operation.

, or par tial rotation.

l Like letters of reference referto like parts in the several gures of the drawings.

The letterA represents a base-frame of any suitable construction adapted to support the parts lot the machine in position for rela- Upon this frame the concentrating and amalgamating cylinder Bis supported and suitably. mollnted for motion to produce ycentrifugal force, suchl as acomplete In the present illustration the cylinder is oscillated through a partial rotation, andone means for accomplishillg this motion is shown.v bythe parallel bars C,- which are secured to a connector C', connected with the operating mechanism and to a cross-bar c2, pivoted to the base upon which the machine rests and to each of the bars C. The base-plate G for the cylinder is suitably pivoted to the parallel .bars C, as shown by dotted lines at C3 inI Fig. 3 and also shown in Fig. vG. The mounting of one cylinder has been described; but .it is obvious that a plurality of cylinders may be used, as shown in the drawings, and each similarly mounted. A

As showing one form of driving mechanism l adapted for the operation of the parts I have disclosed a driving-shaft c4, suitably journaled in standards A' and supplied at one end with a crank C5 for use when it is desiredto drive the machine by hand, while a drivingpulley CG is supplied for the application of other'suitable motive power. Upon the shaft Ci a band-pulley CT is secured, from which a driving-belt C8 extends to a pulley C9 upon a counter-shaft C10. At each end of this shaft crank-wheels C11 are secured, and from the same ptmen C12 extend and are pivotally connected to slide-bars G13, which in turn are connected by the`- links C14, pivoted tothe opposite connectors or bars G'C' to produce an alternate oscillation thereof. This movement 'Y reciprocates the parallel bars C in opposite directions and oscillates the cylinder pivoted thereto to produce the desired centrifugal movement ofthe contents within the cylinder.

The cylinder B is provided at its top with a hopper-disk B', having a central feed-opening B2, adapted to feed into the cylinder orepulp delivered thereto from ya battery of stamps or any other desired source. This opening B2 discharges the pulp at the center of an amalgamating-tray B3, which is of less diameter than the cylinder and supported within the same by brackets B4, so as to leave an annular space between the tray and the cylinder through which the ore which has not been amalgamated upon the tray will fall to the lower portion of the cylinder. The tray is provided with the usual amalgamating metal, which is retained upon the tray by means of a rim The lower portion of the cylinder is also provided with suitable amalgamating substances and with a dischargepipe B1,centrally disposed therein and extending through the bottom of the cylinder. This pipe is provided with an adjustably-telescoping section B7, through which the lighter material and waste which are driven to the center of the cylinder by the centrifugal lnotion may be discharged. A sight-glass BS is also provided, through which the amount of metal collected in the bottom ot' the cylinder may be observed.

The discharge of the heavier matter within the cylinder, which comprises the valuable metal, is eected by means of a needle-valve D, which is automatically operated by centrifugal force, secured in the oscillation of the cylinder B. This valve is shown in detail in Fig. 4 and is pivoted to a discharge-casing D', as shown at D2. The valve Ds completely fills an`d closes the discharge-opening from the cylinder. 'This valve D3 is disposed at an angle to the lever D, upon the outer end of which an adjustable weight D4 may be secured by means of a pin D5, passing through the same and an aperture in the end ot' the lever. When an oscillatory movementis given the cylinder, the lever D will be thrown to the position shown by dotted lines in Fig. 4 and the restoring-spring D11, which is connected to the valve-lever by means of a link D7, placed under tension. The reaction of this spring restores the valve to its closed position, while the movement of the valve-lever may be regulated in extent by means of the stop-plate D8, having a series of recesses D9 therein adapted to engage a fixed member D10, carried upon the discharge-casing D. This plate is normally held in contact with the fixed member by means of the spring D11, secured to the casing, but may be raised and adjusted by placing this spring under tension. The plate Ds is provided with a contact-face D11, extending into the path of travel of the lever D, so as to limit the extent of movement of said lever dependent upon the adjusted position of the plate. Il in operating the cylinder it be desired to prevent a discharge at any time,l the valve and lever may be held in a closed position by means of the lock-hook D13, pivoted upon the casing D', so that. it may be swung over and engaged with an aperture in the lever D to secure the latter against movement, as shown in Fig. 3. The valve-lever is protected by a suitable guard-plate D14, while the dimensions and proportions of the several parts are suitably determined to effect the opening of the valve to an extent relative to the speed of oscillation of the cylinder. The

metal passing through this valve is discharged into the chamber D15 and thence through an aperture D16, passing into the spout D17. This spout discharges into a channel or conduit E, suitably supported beneath the same and extending to the opposite side of the machine, where a delivery-spout E is provided. These conduits may be lined with amalgamatingplates, and if two cylinders be located side by side the receiving end of the conduit may be extended, as at E2, to receive from both discharge-spouts. The materialpassingfrom the spout E flows into any suitable form of settling-tank-for instance, as indicated at E-from which the water may escape and the heavier material settle to the bottom. The spout E is mounted so as to permit a lateral shifting to discharge into either settling-tank.

The waste material which is discharged from the cylinder through the pipe B7 is received by the tank F beneath the cylinder, which is provided with a series of discharge doors or valves F', opening onto a series of tables F2, mounted in a frame F3, which is pivoted at its upper end and adapted to be adj usted in inclination by means of a lever F, pivotally mounted on the frame and adapted at its lower end to bear against the base A, upon which the machine is mounted. It will be seen that the adjustment of this lever will raise or lower the free end of the frame carrying these tables, and thus determine the rapidity of the fiow of the material over the same. The tables F2 maybe provided with any desired form of amalgamating or ore-collectin g surface in order to test the waste from the cylinder and determine whether any valuable metal has escaped the amalgamating and concentrating processes therein. In order to facilitate the passage of the waste over the table, additional water may be introduced into the tank F by any desired means-for instance, from a reservoir F5 at one end of the tank. It' it is not desired to use the tables, the doors or valves F may be closed and the waste material discharged from a suitable opening F7 at one end of the tank F and conveyed away by a chute F6. The primary purpose of the testing-tables F2 is to determine the character of work done by the cylinders upon different characters of ores, and it will be evident that if a small amount of the waste be tested upon the table and found free from valuable metal the remainder may be permitted to escape through the discharge-chute. The needle-valve D has been shown as applied to opposite sides of each cylinder B; but the number and location of these valves may be varied relative to the capacity of the cylinder, while the extent to which the valve is opened depends upon the amount of valuable metal collected at the bottom of the cyl- IOO IIO

inder, and is thus governed largely by the 5that the'operation of the invention will be clearly understood. The pulp from the stamps `first falls u pon the tray B3and alarge percentage of thefree metal therein is amalgamated upon this surface. I over the edge Aof the tray by the centrifugal motion of the cylinder and passes to the bot-- tom thereof, where this same motion causes the lighter material or waste to move toward the central discharge-pipe, while the heavier metallic particles cling to the wall of the cyluinder and are freely discharged through the ,needle-,valve The adjustable Acentral discharge-tube permits the collection of sufficient material in the bottom of the cylinder topermit the settlementV ofthe heavier or more valuable metals tothe lower portion,A

i' liwhere they lmay be discharged.' As hereinbefore stated, the waste from the cylinder maybe conducted away or passed over the supplemental amalgamating-tables for testing or the recovery of other valuable material, if found tobe contained in Ithe Waste.

The tank F beneath thecylinders B is provided with a water-channel H, extending around the edge thereof from the reservoir F5 to a discharge F6. The front portion of this tank is provided with an inclined bottom H, Fig. 7, which leads -to the doors F', opening onto the tables F2. Opposite the discharge foreach of the cylinders an opening H3 permits the Water-from the channel 'H'l to fiow upon the table, and this fiowmay be directed toward one or more discharge-doors by means of a pivoted switch-valve H4, the point of one end of which is adapted to lie against either side of the opening H3, as shown by dotted lines in Fig. 6, or centrally of said opening, as shown by full lines. It will be seen that if the valve be shifted to one side the entire body of Water will be permitted to pass out of one door, carrying therewith the waste material discharged from the cylinder', while if the valve be centrally disposed the fiow and amount of water is divided between the doors upon adjacent sides of the valve and cylinder. In this manner the desired amount of water may be used upon the table F2 and either one or both of said tables used. If it be desired to discharge the waste through the waste material will pass through the openings H3 into the water-channel and thence through the discharge-port F7 into the chute F6.

Attention is particularly called to the reciprocatory motion by which the centrifugal force produced in the motion of the cylinders is alternated, so that the heavier material within the cylinder shall not acquire the centrifugal motion, and thereby lie perfectly still against the rim of the drum, as would be the case if the motion were produced by a complete rotation. The partial rotation or oscil- The remainder is forced chute F6, the doors F may be closed, and the lation distributes or'tu'mbles the material in such manner as to secure a thorough separation and lead the lighter particles toward the discharge-pipe at the center of the cylinder. An important feature of this pipe is the adjustable section at its upperend, by means of which the sedimentary capacity of the cylindermay be varied to retain any desired amount of material below the point of discharge as may be found necessary in operating upon dierent classes of ore.

It may also be stated that the invention is not confined to the use of amalgamating- `platesor material upon the tables F2, as the ore may be retained by any collecting means-- 'for instance, a covering of canton-fiannel or similar material-'which retains the heavier particles of the waste passing through the tables. j

It is obvious that changes may be made in the details of construction and configuration of the several parts without departing from the spirit of the invention as defined by the appended claims, as the form of apparatus now illustrated is but one of numerous constructions and arrangements of parts contemplated by this invention.
